Abstract

A bus architecture includes address lines, data lines, and control signals to allow a processor to communicate with a VLSI gate array. The address lines are interpreted by the VLSI gate array to select either multi-bit registers or single bit designators resident on the VLSI gate array depending on which control signal is received from the processor. Dual address decode logic on the VLSI gate array senses control signals indicating a request to read from a register, write to a register, and set, clear, or test a designator, and decodes the address received to select the appropriate storage location for the requested function.
